Hello, I’m Lenko Donchev. I’m Software Engineer.

I’ve been developing software since 1999. Back then I started by building Internet meta search engine in Perl. I sold the search engine. I have used many programming languages but Perl still has a special place in my heart.

I have experience in the following domains:

  • security, identity and access management
  • cloud-based platforms
  • educational(K-12) and clinical assessments
  • petabyte scale financial trading infrastructure
  • financial trading systems, fault-tolerant real-time feed handlers and market data gateways
  • distributed machine learning - betting advisor for betting on horse racing
  • Internet of things big data platform for retail analytics
  • distributed poker game server
  • casino and arcade games

In my free time I like to play violin.

The best way to contact me is through email:

I can also be found on Speaker Deck, Keybase, Twitter, Github and LinkedIn.
